Credentials not working for Bing Maps Geocoding API

I am using the geocodeing api to get Lat and Lon data  showen below: 

let 
Location = (State as text, Suburb as text, Pcode as text, Address as text)=>

let
    Source = Xml.Tables(Web.Contents("http://dev.virtualearth.net/REST/v1/Locations?countryRegion=""US"""
    &"&adminDistrict=" & State
    &"&locality=" & Suburb
    &"&postalCode=" & Pcode
    &"&addressLine=" & Address
    &"&o=xml&key=Ak1LEVAlLWaUn....................................")),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Copyright", type text}, {"BrandLogoUri", type text}, {"StatusCode", Int64.Type}, {"StatusDescription", type text}, {"AuthenticationResultCode", type text}, {"TraceId", type text}}),
    #"Removed Other Columns" = Table.SelectColumns(#"Changed Type",{"ResourceSets"}),
    #"Expanded ResourceSets" = Table.ExpandTableColumn(#"Removed Other Columns", "ResourceSets", {"ResourceSet"}, {"ResourceSet"}),
    #"Expanded ResourceSet" = Table.ExpandTableColumn(#"Expanded ResourceSets", "ResourceSet", {"Resources"}, {"Resources"}),
    #"Expanded Resources" = Table.ExpandTableColumn(#"Expanded ResourceSet", "Resources", {"Location"}, {"Location"}),
    #"Expanded Location" = Table.ExpandTableColumn(#"Expanded Resources", "Location", {"Address", "Confidence", "GeocodePoint"}, {"Address", "Confidence", "GeocodePoint"}),
    #"Expanded Address" = Table.ExpandTableColumn(#"Expanded Location", "Address", {"FormattedAddress"}, {"FormattedAddress"}),
    #"Expanded GeocodePoint" = Table.ExpandTableColumn(#"Expanded Address", "GeocodePoint", {"Latitude", "Longitude", "UsageType"}, {"Latitude", "Longitude", "UsageType"}),
    #"Filtered Rows" = Table.SelectRows(#"Expanded GeocodePoint", each ([UsageType] = "Display"))
in
    #"Filtered Rows"

in 
Location

I then used this code to invoke a custom function that pulls in the info for state, suburb, Pcode and address. This works when I limit the data to around 10 rows as showen below:

However when I remove the index filter to include more than ~ 10 rows I start to get a credential error message that I am not able to resolve (showen below):

None of the credential options are working and am stuck on how to fix this. 

Thanks!
